BUCKET.

VBpeceation o! Letten Patent.

Patented Dec. 8, 1908.

Application led August 21, 1907. Serial No. 389,434.

To all whom it 'may concern:

Be it known that I, HERBERT S. ATKINSON, a citizen of the United. States, and a resident of the town 'of Weehawken, in the county of Hudson and State of New Jerse have invented certain new and usefu Improvements in Buckets, of which the following isa description.

This invention relates to an improvement in buckets such as are commonly employed for loading, unloading, dredging and similar work, and in the present instance I have shown such im rovements as are embodied in a bucket o' the clam-shell type, although it is of course to be understood that such im rovements are applicable to buckets of ot 1er types.

In carrying out this invention, it is my purpose to provide a bucket embracin the desirable features of simplicity, dura ility and strenfrth, and furthermore, to so construct and arrange various parts going to make up the entire structure, that such bucket will work easily and positively. Furthermore, a bucket constructed as shown ma be worked continuously and for long periods of time without being subjected to deran gement and injury.

This invention consists in the construction, combination and arrangement of parts set forth in and falling within the scope -of the appended claims.

Referring now to the accompanying drawings in detail, Figure 1 is e pers ective view of a clam-shell bucket provi ed with my improvement, such bucket being shown in ope'nl position, the loperating ro es in the bucket, which are arranged in t e manner well known, being omitted. Fig. 2 is a detail view oi a portion of the center' wheel or power sheave of the bucket. Fig. 3 is a Sectional view taken through the sheave wheel and showing the manner of securing the operatinf chains thereto. Fig. 4 is a view in side elevation of the sheave wheel, showing the manner of attaching Y the rope guard to the shaft thereof. Fig. 5 is a view 1n elevation of tbe @heaveA wheel showing the rope guard in connection therewith, and also illustratingba portion of the bucket and the Inanner of racing the same.

Referring now to the accompanying drawings in detail, A and B indicate the sections of the bucket ivotally connected together by the shaft which may be termed the uwer-wheel shaft. Each of these sections ls provided, adjacent to the point where it is pivoted to the shaft, with a cross brace 1 and an angle brace 2, the angular arms 3--3 merging in a central portion at approxi-l mately the control part oi the cross brace 1. These braces are intended to impart strength and rigidity to the bucket sections at the point where they are hinged to the shaft C and where they are subjected to considerable strain.

Each of the sections is provided with side lugs 5, havingr secured thereto one end of the side connectln ends of such ars being connected by the pivot 7 passing throu yh the bearing 8, the construction being suc that the bucket sections may swing upon such pivot and be opened and closed in the well known manner. Upon the shaft C is mounted the wheel D bars 6, the opposite or top havin .a hub section 9 for passage of the I shaft the central portion of such hub being enlarged as is shown at 10.

The eriphery of the wheel section 11 is circuin erentially grooved, as at 12, to receive the o erating rope of the bucket (not sl1own).` e end portions of thc hub 9 are also grooved or cut away at 13-l3, to receive duplex sections 14-'1 4 of the chains 15, the opposite ends of such chains being suitably connected to suspe og rods iti-46. The end links 17, 17--1, i7 oi the duplex ortions of the chains tit into transverse ores or slots 18, 18--18, 18, while a longi tudinal bore 19 extends alongside the bore or passe e of the shaft C, the bore 19 being def signe to receive the fastening pin 20, which passes through the links 17, such pin providingmeans whereb t? 1- links are fastened to the hub. It willlie noted that between the links 17 of each duplex chain section the pin 20 is ex osed, the grooved or cutaway portion 13 orming practically a continuation of the bore 19.

By such a construction as just described, the chain section ma be easily and readily connected to and isconnccted from the wheel D.

In the present instance, I have` shownthe chains hereinemployed as each comprising a duplex section and e. single section, so constructed lthat when the sheave wheel has made one complete rotation, asin the closing of the bucket, the duplex section will wrap completely around the sheave on the grooved ends of the hubfwithout such duplex section overla ping; that is to say the duplex section o ea'cn chain is just long enough to e11- circleI the grooved end ot the hub to which it is attached, and the single section 15 of each chain, as the power wheel or sheave continues to rotate in the action of closing the bucket, will wrap onthe center section of such grooved hub in between the duplex section of the chain and without coming in contact with the latter section, until the bucket is closed. But l. Wish it to be understood that l do not limit myself to the use of a chain i-.nzfufvl :it o. duplex section and u. single secicn. ,in -rnr instances, :t may be desirable to employ another type of chain, and in my cri-pending application Serial No. 3?" Uran 3, hin r shown certain types of ehnin which are particularly applicable to buckets of vari-lus ins in b ig. i, the construction nl' the loearinfz,r b is shown, being in iol-In a scmi-circnlan hood with circular end plates S und provided lindern if isxrvd intervals along its` IenUth with spacing lugs through which an the cud plates passes the pivot 7. The spaces between adjacent lugs form recesses for the reception ol the ends of side bars (i and suspenfiing rods` lo und 16A Any great lulersl mownient ol the ends ol the bans G and rods l() on lire pivot 7 is thus prevented` ln Fig. l l have shown inclined braces or strips 2l connected at their upper ends, as at 22, to thc sidi` bar fi, and at their lower ends convergingr and beinpr fastened, as at 225, to the central lugs .54 of the bucket sections. l provide these braces lor the purpose of maintaining; the chains suspended in proper anneinent relative to the hub section. .lt will benoted that, as heretofore described, the chains are connected to suspending rods lwl, and that these rods are in turn connected to the )ivot 7. By employing the braces 2l to hoid the side bars 6 spaced apart, and constructing the hood bearing 8, as described, the tendency of the chains 15 to be deranged by an); sidcwise thrust or strain upon the bearing S is obviated, and interference with the proper wrapping or ceiling of the chains is thus avoid-eu. -v

ln Figs, l, Li :unl 5 i have sbonn thc wheel i) as proridwl with a rope guard, the latter comprisan, tlnl .spider lV, haring the ond wels 2:', perforated to permit the passing of the shalt Lf, und with wels arc connected by means of impuls: guard arms 2li; each ol' which, nl a point adjacent to thc periphery of the wheel has a groovcd shoe 21". lt will bc evident that the rope encirrlinpy the shcavc runs between the groove in the periphery of the sheave and the groove .n the guard shoe.

l have found by experience that a bucket constructed in the manner'herein described can benvorked repeatedly and freely without como:

chains becoming fouled, disengaged or uis turbcd. Furthermore, in the case of breaking or other accident to either the chains or the means connectingr the same to the sheave, such chain may be easily removed by simply withdrawing the bar 2U from the bore 19 and the broken part replaced without any considerable labor or any great loss of time. Furthermore, the parts of such bucket are readily accessible in case it should be necessary to make Such repairs, or to dismantle the bucket.

W'hile l have herein shown and described my improvements as applied lo n "clanishell" typcof bucket, it mii ofcourse be understood that it is applicable also to other types, and furthermore, l wish it to be understood that l dfi not confine myself to all the precise details oll c nstruclion herein shown and described, as snmliiicntion and variation may be made without departing from the spirit of the invention or scope of the claims.
